When we meet difficulties, most of us will be feeling distressed, just like the whole world is down and there is no hope for tomorrow. When we look back after many years, the difficulties at that time are just small matters, only if we can hold on to these. Life is wonderful, there is no need to let down on life when we meet difficulties, like a popular song“How can we see the rainbow without the storm”. Once I failed on the exam, I feel my world is over, I couldn’t eat well, I just let my parents down, I was so guilty about it. My teacher told me that the exam was not a big deal, I should forget it and kept moving on. Since than, I work hard and trying to forget it. Now when I look back on the failing exam, I think it is not a big deal.
